This jumper dress requires no special setup; it's a straightforward pull-on garment. It is designed to fit as a standard UK Size 20 for adults. For optimal care and to maintain its quality, the dress is machine washable. Always check the garment label for specific temperature settings and drying instructions to prevent shrinkage or damage to the knitted fabric. Avoid harsh detergents and bleach. It's recommended to air dry flat to help maintain the dress's shape and prevent stretching or distorting the knit. Store folded rather than hung to avoid stretching out the fabric.
